1. We set up TRB (tapered rolling bearings) on this lathe to increase the rigidity of the spindle.

2. Big spindle bore and double chuck allows clamp and process big diameter pipes;The spindle bore is very large and set up double chucks both front and back and you can choose electric chucks as you like.

4. The slide rail f saddle is treated by wear-resisting layer coated, to avoid the crawling.

5. There are two types of speed change: Manual and step less.

6. Set up self lubrication system, and easy to maintain.

7.Integral machine bed adopts high strength iron to relize high rigidity and precision;

Application:

QK series CNC Pipe threading lathe machine is mainly designed to process all kinds of internal and external pipe threads including metric,inch,module,DP and taper threads,as well as having all the common functions of normal CNC lathe such as processing the inner bore and end face of shafts and disks.

This series lathe machine is widely used in industries including petroleum exploiting,coal and minerals mining,chemical piping and geological prospecting,it is high-efficiency equipment in processing and repairing drilling pipe,drilling rod,thread coupling and so on.

We use electric furnace smelting, resin sand molding casting technology,avoid sand holes, stoma casting internal defect effectively, all the accessories are assayed by imported spectrum analyzer, it assures the quality of the casting . The casting had been through second thermal aging treatment with good stability.

The bed of floor type is the whole structure. The rigidity and width of guide way on the bed of lathe is good enough. The guide way is through high-frequency quenching, the slide guide way joint SD compound soft belt. to make more wear-resisting and lower friction factor. The lead screw is the whole structure (not butt). The saddle is wider and thicker than before, the machine is running more stable. And the cutting ability is better.

The 3 boxes of lathe were processed by Taiwan’s CNC boring and milling machine center. The other tools are processed by CNC lathe and machine center to ensure the precision of the box and tools.

First step of the accuracy test of the equipment is testing the repeat accuracy of X and Y axis with Renishaw laser interometer imported from Britain. After that, inspecting and accepting the whole equipment based on the enterprise standards, guarantee the accuracy of the machine tool.
